The five Taiwanese samples of P. microdon included in this analysis formed a single cluster, distinct from, but sister to, the P. microdon samples from the southern Madagascar Ridge and the Mid-Atlantic Ridge ( Figure 7 ). These results challenge the currently accepted view that this species is circumglobal in distribution (e.g. Compagno et al. , 2005) and suggest that the western North Pacific population is distinct from the Northern Atlantic/ southwestern Indian populations. A taxonomic revision of this genus is required to determine whether these two clades represent distinct species and if so, determine whether Pseudotriakis acrales Jordan & Snyder 1904 described from Suruga Bay in Japan should be resurrected as a valid species.
